FURNITURE LEG SLIDE.

Application filed August 15, 1925. Serial No. 50,429.

This invention relates to what is commonly called a furniture slide formed from a single piece of sheet metal.

The chief object of the invention is to form a slide of the foregoing character so that it will have certain structural characteristics heretofore not found in the devices of this type.

The chief feature of the invention consists in the formation of the several anchorage portions with a beveled or tapered face, and a cent-ral'bearing portion of increasedthiokness during the blanking of the slide or immediatelyprior to the formation of-the blank into cup form.

Another feature of the invention consists in the provision of a plurality of prongs arranged in spaced relation about the external periphery of the slide and the provision of a plurality of intermediately positioned wedges, the latter having a relatively low height and a relatively wide base compared to the height and base width ofthe prong.

Another feature of the invention consists in the ofi'setting laterally of the prongs and preferably the curvature of said prongs whether offset. or otherwise as pointed out hereinafter.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims: f

In the drawings Fig. 1 is a top plan view of a slide blank showing the outline thereof. Fig.2 is an edge elevation of one form of blank showing the swedging or tapering of the prong. Fig. 3 is a similar view of a different formation of the prong. Fig. t is a similar view of another formation of prong, thisforination being positioned intermediate that shown'in Figs.'2 and 3. Fi

5 is a side elevational view of the simplest v type of slide embodying the invention. Fig.

6 is a central sectional view thereof; Fig. 7

is a similar view of a modified form of the invention. Fig. 8 is a view similar toFigs;

6 and 7 and of a still further modified form of the invention. Fig. 9 is a top plan view of a slide, the prongs of which are formed as shown in Fig. 2. Fig. 10 is a top plan view similar to Fig. 9 but of a modified form of the invention wherein the prongs are offset laterally and inwardly with respect to the the marginal portion of the slide and are curved with their concave curvatures outwardly po sitioned. Fig. 11 is av top plan view show mg a further modification. Fig. 12 is a central sectional view through one of the prongs shown in Fig. 11 and a portion of the slide and is taken on line 12--12 of Fig. 11. Fig. 13 is a view similar to Fig. 11 but of a modified form of slidev wherein the off-setting of the prong extends into and substantially through the marginal zone of the slide. Fig. 14: is a view similar to Fig. 12 and is taken on line 14 -14 of Fig- 13. Fig. 15 is a top plan view of a modified form of the invention, wherein the prong is corrugated. Fig. 16 is a similar view of a modified form of Fig. 15. wherein the prong is offset laterally and outwardly with respect to the marginal zone. Fig. 17 is a top plan view of a modified form of the invention and the preferred form, to wit, which all the claims read upon.

In the drawings 10' indicates a substantially flat bearing zone. 11 an intermediate zone and 12a marginal zone. A plurality of prongs, and herein three are illustrated, are indicated in the several figures by the numeral 14,.and interposed between said prongs and also integral with the marginal zone are wedges 15. The wedges 15 have a relatively low height and a relatively wide base, while the prongs 14 have a relatively highheight and a relatively narrow base. The foregoing constitutes the simplest form of the invention and as will be observed from Figs. 1 and 5, said prongs and wedges are substantially triangular in outline.

In Fig. 2 an edge view, of the blank adjacent the prong is illustrated and shows the formation of the taper ofthe prong by the swedging or flattening of the face 14*, the face 14 in this form beingcontinuous with the exterior of the marginal zone. In Fig. 3 a reverse form of prong is illustrated and in this form the flat face 115i is continuous with the interior surface of the marginal zone 12, while the inclined 'face 114; is in' olined to the exterior of the marginal zone. In Fig. lthe marginal zone 12 supports the prong 14 whichhas its faces 214i and 214i shown inclined to the exterior and interior surfaces of the marginal zone 12. The foregoing arrangement, to wit, with the marginal zone continued upwardly throughout the prong, is shown clearly in Fig. 9 and corresponds to that form of the invention shown in Fig. 2.

As shown clearly in the several figures, particularly Figs- 6: to Sand 12 and 14, the

central bearing zone 10. is of considerably greater thickness than the intermediate zone 11 and the marginal zone 12. This increased thickness not only acts as astill'ener, but also provides increased metal for wear, thereby insuring a longer life in a slide of this character than has heretofore been obtainable. This increased thickness is formed by swedg ing or otherwise and is produced in the blank prior to its final formation in cup design, shown in F 5.

The wedges 15 are herein illustrated as provided with their exterior faces a continuation of the marginal zone thus being comparable to the type of construction shown in Fig. 2' for the prcngf The prongs and the wedges'are both herein shown triangular in outline. As shown clearly in Figs. and 6, the inclined edges of the bases and prongs have common intersections coincident with the marginal Zone. As shown in Fig. 7, said intersections are formed by a curved notch or fillet arrangementindicated by the numeral 116. Also as indicated in Fig. 8 the wedge, while substantially triangular in outline, is curved as at 1 and thus is of spherical triangle character.

In Figs. 11 to 16 inclusive, modified forms of the invention are illustrated and the several figures show a laterally offset prong variously arranged. In Figs. 11 and12 the prong- 314 is shown offset laterally and outwardly with respect to the marginal zone and'is integral therewith. In Figs 13 and 1.4 the prong 414 is offset laterally and outwardly from the marginal zone. but inthis form of the invention the portion'412 ofthe marginalzone is also oil'setoutwardly and laterally so that the prong extends upwardly from said outward ofi'set marginal portion 412.

In Fig. 15 there is illustrated a further modified form of the invention, wherein the prong is not only of a curved: nature such as shown in Figs. 11 to 14 inclusive, but this prong 514 is provided with a corrugated out line, having an exterior surface 514 and an interior surface 514 In Fig. 16 a combination of the forms shown in Figs. 14 and 15 is illustrated, and in this form the corrugated' prong 614 is shown provided with the exterior surface 614 and the interior surface 614. In this'form of the invention, how' ever, the entire prong is offset laterally and outwardly by the portion 612 and in this respect is similar to the form of the invention shown in Figs. 13 and 14.

The specific form of the invention elected is a combination of the several variations or modifications illustrated herein in the sev eral figures and comprises a central bearing zone of increased thickness, an intermediate zone, a marginal zone having outwardly projecti-ng lateral portions, corrugated tapered triangularly out-lined prongs extending upwardly therefrom. and tape-red triangularly outlined wed interposed therebetween and integral with the marginal zone, said pron- 's and" wedges having notched 01' filleted connections.

Herein the aforesaid specific form upon which all the claims rcad'and described immediately preceding is illustrated in Fig. 17 in which the like parts are similarly numbered, all numerals being of the seven hundred series.

The invention claimed is: y

1. In a sheet metal slide. the combination of amarginal zone, a substanti l lyflatcentral bearing zone of greater thickness than the ma -nal zone connected thereto, a plurality of tapered prongs, and a similar nuinber of tapered wedges interposed between said prongs.

2. In a sheet metal slide. the combination of a marginal zone, and a plurality of prongs integral therewith and offset late-rally and outwardly from said marginal zone and including a laterally and outwardly offset-p01 tion of the marginal zone.

3. In a sheet metal slide the combina tion of a marginal zone, and a plurality of prongs each having a greater width than thickness and integral with said zone; each having both of its wider faces inclinedthereto and towards each other for tapering purposes.

4. In a sheet metal slide, a marginal zone, and a plurality of triangular wedges each having a base greater thanits height and: integral with said zone, each having one of its faces inclined thereto for tapering pin poses.

5. In a sheet metal slide the combination of a n larginal zone, a plurality of prongs in=- tegral with said zone, anda plurality of wedges also integral therewith and inter posed between said prongs, said zone having an interrupting notch between each: prong and wedge. I

In witness whereof, I have hereunto attired my signature.
